In this paper, a microstrip diplexer with a very compact size is presented for 5G networks. The proposed diplexer operates at 3.5 GHz and 4.2 GHz, which fall within the 5G extended C-band (3.3–4.2 GHz ...
We present the design and practical implementation of a microstrip diplexer based on the wave discrimination property associated with the electromagnetically induced transparency (EIT)-like effect.
